The design of a new wideband modular sound absorber

A modular system of acoustic treatment for use in a wide range of types of studios, control rooms, and other areas is discussed. Although the system at present in use is generally satisfactory, several defects are identified. The design of a new module intended to absorb sound over the entire audio frequency range and to overcome these defects is discussed and the results of some measurements are presented. The final design for the new module is described and its performance is compared with that of the combination of the earlier modules most commonly used in small and medium sized rooms. The proposed module is far from ideal and will probably prove to be more expensive to manufacture.
